Quantifying Acoustic Uncertainty Due to Marine Mammals and Fish Near the Shelfbreak Front Off Cape Hatteras
Abstract
The long term goals of our work on acoustic uncertainty due to fish and marine mammals are to: 1) understand the nature of low-to-medium frequency (100-2000 Hz) acoustic scattering (specifically reverberation and attenuation) by fish schools and larger marine mammals, 2) advance our acoustic methods of quantitatively imaging fish schools and tracking vocalizing marine mammals, and 3) understand the correlation between the detailed physical oceanography and the biology and acoustics. Our primary objectives this year were: 1) perform our year two major experiment off Cape Hatteras, N.C. to measure the acoustics, biology, and physical oceanography of fish schools and (if present) marine mammals, 2) continue analysis of our year one survey cruise data, and 3) compare the year one and year two results, as this comments on the variability in the ecosystem.
